New cards

What are the organs of the digestive system?

Mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas.

2
New cards

What does the mouth do?

The mouth begins the process of digestion by chewing and breaking down food into smaller pieces.

3
New cards

What does the esophagus do?

The esophagus transports food from the mouth to the stomach through peristalsis.

4
New cards

What does the stomach do?

The stomach secretes gastric juices to break down food further and mixes it into a semi-liquid form called chyme.

5
New cards

What does the small intestine do?

The small intestine absorbs nutrients from the chyme into the bloodstream for distribution to the body.

6
New cards

What does the large intestine do?

The large intestine absorbs water and electrolytes from undigested food, forming feces.

7
New cards

What does the liver do?

The liver produces bile, which aids in the digestion and absorption of fats.

8
New cards

What does the gallbladder do?

The gallbladder stores and releases bile into the small intestine.

9

12
New cards

What does the pharynx do?

It serves as a passage for both air and food.

13
New cards

They are two branches that carry air into the lungs.

16
New cards

What do the lungs do?

They are the main organs of respiration, where oxygen is taken in and carbon dioxide is expelled.

17
New cards

What does the diaphragm do?

It is a muscle that aids in the process of breathing by contracting and relaxing.

18
New cards

What are the major organs of the cardiovascular system?

Heart, blood vessels, and blood.

19
New cards

What does the heart do?

The heart is a muscular organ that pumps blood throughout the body. It consists of four chambers - two atria and two ventricles. The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The left side receives oxygenated blood from the lungs and pumps it to the rest of the body.

20
New cards

What do the blood vessels do?

There are three types of blood vessels - arteries, veins, and capillaries.

Arteries carry oxygenated blood away from the heart to the body's tissues.

Veins carry deoxygenated blood back to the heart.

Capillaries are tiny blood vessels that connect arteries and veins, allowing for the exchange of oxygen, nutrients, and waste products between the blood and tissues.

21
New cards

What does the blood do?

Blood is a fluid connective tissue that transports oxygen, nutrients, hormones, and waste products throughout the body. It consists of red blood cells, white blood cells, platelets, and plasma. Red blood cells carry oxygen, white blood cells fight infections, platelets help in blood clotting, and plasma carries nutrients and waste products.

22
New cards

What are the accessory organs of the digestive system?

The liver, pancreas, and gallbladder are accessory organs.

23
New cards

Describe the anatomy of the heart.

The heart is a muscular organ located in the chest cavity. It consists of four chambers: two atria and two ventricles. The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs. The atria contract to pump blood into the ventricles. The right ventricle pumps deoxygenated blood to the lungs, while the left ventricle pumps oxygenated blood to the rest of the body. The heart is surrounded by a protective sac called the pericardium and is supplied with oxygen and nutrients by the coronary arteries. The heart's rhythmic contractions are controlled by electrical signals from the sinoatrial (SA) node and atrioventricular (AV) node.

24
New cards

Describe the flow of blood through the heart.

The flow of blood through the heart can be described as follows:

  1. Blood that is low in oxygen and high in carbon dioxide enters the right atrium from the superior and inferior vena cava.

  2. The right atrium contracts, forcing the blood through the tricuspid valve into the right ventricle.

  3. The right ventricle contracts, pumping the blood through the pulmonary valve into the pulmonary artery.

  4. The pulmonary artery carries the blood to the lungs, where it picks up oxygen and gets rid of carbon dioxide.

  5. The blood is now high in oxygen and low in carbon dioxide.

  6. It returns to the heart through the pulmonary veins and enters the left atrium.

  7. The left atrium contracts, pushing the blood through the mitral valve into the left ventricle.

  8. The left ventricle contracts, pumping the oxygenated blood through the aortic valve into the aorta.

  9. The aorta distributes the oxygenated blood to the rest of the body.

  10. The cycle repeats as deoxygenated blood returns to the heart via the vena cava.

25
New cards

Define pulse.

Pulse refers to the rhythmic expansion and contraction of arteries as blood is pumped through them by the heart. It is typically measured by counting the number of beats per minute at certain points in the body, such as the wrist or neck.

26
New cards

Define blood pressure.

Blood pressure is the force exerted by the blood against the walls of the arteries as the heart pumps it around the body. It is measured using two values: systolic pressure (the pressure when the heart contracts) and diastolic pressure (the pressure when the heart relaxes). Blood pressure is an important indicator of cardiovascular health.

27
New cards

What are some common cardiovascular system pathology terms?

Atherosclerosis, Myocardial infarction, Hypertension, Arrhythmia, Congestive heart failure, Coronary artery disease, Valvular heart disease, Cardiomyopathy, Peripheral artery disease, and Stroke.

28
New cards

What is an atherosclerosis?

A condition where plaque builds up in the arteries, causing them to narrow and harden.

29
New cards

What is a myocardial infarction?

Also known as a heart attack, it occurs when blood flow to the heart muscle is blocked, leading to tissue damage.

30
New cards

What is hypertension?

High blood pressure, which can strain the heart and blood vessels.

31
New cards

What is an arrythmia?

An irregular heartbeat, which can be too fast, too slow, or irregular in rhythm.

32
New cards

What is congestive heart failure?

A condition where the heart is unable to pump enough blood to meet the body's needs.

33
New cards

What is coronary artery disease?

38
New cards

What do arteries do?

These vessels carry oxygenated blood away from the heart to the body's tissues. They have thick, elastic walls that can withstand high pressure. Arteries branch into smaller vessels called arterioles.

39
New cards

What do veins do?

Veins carry deoxygenated blood back to the heart from the body's tissues. They have thinner walls compared to arteries and contain valves to prevent backflow. Veins merge into larger vessels called venules.

40
New cards

What do capillaries do?

Capillaries are tiny, thin-walled vessels that connect arteries and veins. They allow for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. Capillaries have a large surface area and slow blood flow to facilitate this exchange.

41
New cards

What are the major organs of the cardiovascular system?

Heart, blood vessels, and blood.

42
New cards

What does the heart do?

It pumps oxygenated blood to the body and deoxygenated blood to the lungs.

43
New cards

What do the blood vessels do?
