Transport in Animals (2.25-2.29)

Semilunar valves

________ are found within the pulmonary arteries and the aorta.

Lymphocytes

________- produces antibodies and antitoxins.

Haemoglobin:

iron containing pigment pick Oxygen and drops.

Septum

________: Muscle wall that seperates two sides of the heart preventing the mixing of oxygenated and deoxygenated blood.

Aspirin

________: Dilutes blood and so reduces blood clotting.

Plasma

________ is forced out of the capillary to become tissue fluid.

Muscle cells

________ in the heart need their own supply of blood to deliver oxygen and glucose.

Arterioles

________: Smaller branches of an artery that eventually form capillaries.

Coronary bypass surgery

________: Piece of blood vessel is taken from patients lef or arm.

Mammals

________ have double circulation and a 4 chambered heart.

Venules

________: Small vessels formed from the joining of the capillaries and combine to form a vein.

blood flows

Deoxygenated ________ from the body to the right atrium through the vena cava.

Angioplasty

________: Catheter threaded through the groin up the blocked vessel.

Walls of capillaries

________ are thin; water dissolved substances can easily leak out of them.

Valves

________: Prevent the backflow of blood and ensure one way flow.

Sensitive cell membrane detecs chemicals

________ produced by pathogen.

coronary arteries

Blood is supplied by ________.

Platelets

________ release chemicals that stimulate the conversion of**== soluble fibrinigen → Insoluble fibrin,==** forming insoluble mesh trapping RBCs and froming a clot.

Main artery

Aorta

Shunt vessels

________: Connect blood directly from arterioles to venules forming an alternative route dor blood flow.

Ventricles

________: Have a thicker muscle wall than the atria because they pump blood at higher pressure.

right ventricle contracts

The ________ (semilunar valve opens) blood is pushed through semilunar valves into pulmonary artery.

‘ Leaky walls

________ allow blood plasma to leak out and forn tissue fluid surrounding cells.

lymphatic system

The ________ is composed of lymphatic vessels which carry "lymph "and lymph nodes which produce lymphocytes for immunity.

Arterioles

________ have muscular /elastic walls that can constrict & dilate in order to regulate blood flow.

Circulatory system

System of blood vessels with a pump and valves to ensure one way flow of blood

RIGHT

recieves deoxygenated blood from body (atrium) pumps to the lungs (ventricle)

LEFT

revieves deoxygenated blood from lungs (atrium) pumps to body (ventricle)

Veins

Carry blood towatds the heart

Septum

Muscle wall that seperates two sides of the heart preventing the mixing of oxygenated and deoxygenated blood

Ventricles

Have a thicker muscle wall than the atria because they pump blood at higher pressure

Atria

The right and left atrium contracts to pump blood into the right and left ventricles respectively

Valves

Prevent the backflow of blood and ensure one way flow

Anaerobic Respiration

Glucose→Lactic acid

Aspirin

Venules

Small vessels formed from the joining of the capillaries and combine to form a vein

Shunt vessels

Connect blood directly from arterioles to venules forming an alternative route dor blood flow

Red Blood Cells

Transport Oxygen from lungs→Respiring tissues

Plasma

Transporting carbon dioxide, digested food, urea, hormones and heat

Plateles

Blood clotting
