Tyler Teas Anatomy Highest Priority

Immediately before blood enters the lungs, it passes through the:

right ventricle

Choose the terms that best complete the following sentence:

The release of ___ from ___ cells in the __ causes blood sugar to rise

Glucagon, alpha cells, pancreas

Which anatomical plane is depicted below?

transverse

***Implantation typically occurs during which time?

secretory phase

***Choose the substance that is created by breakdown of proteins and then excreted by the kindeys

*When body breaks down proteins, you get 3 things:

1.Urea(nitrogenous waste)

2.Carbon dioxide

3.Energy

A primary function of T cells in the immune system is to:

-produce antibodies

-engulf pathogens

-kill infected cells

-trigger inflammation

kills infected cells

-produce antibodies (plasma b cells)

-engulf pathogens (macrophages)

-kill infected cells

-trigger inflammation (histamine causes inflammation through release by mast cells & basophils)

7.The primary function of hemoglobin is to

transport oxygen

red blood cell job-carry oxygen

Red blood cells can carry oxygen because it has hemoglobin(protein) inside it. Hemoglobin is an oxygen carrier

-Inside Hemoglobin are “heme” molecules. *Iron is inside heme

***If hemoglobin doesn’t have iron=can’t carry oxygen

***Which of the following proteins is highly enriched in the epidermis, compared to other layers of skin?

keratin

Starts off as keratinocytes and becomes keratin as it moves up

Which of the following systems controls body functions by the release of chemical messengers?

endocrine

Place the labels in the correct location on the diagram

B, D, E, C, A

Which of the following vitamins is created by bacteria in the intestines?

-vitamin A

-vitamin C

-vitamin D

-vitamin K

vitamin K

-vitamin A (eyesight, liver: carrots)

-vitamin C (citrus fruits, orange)

-vitamin D (sun)

***Which statement correctly describes a process that occurs during formation of a blood clot?

-Platelets aggregate to create a mesh-like structure

-Thrombin catalyzes the conversion of fibrinogen to fibrin

-Vascular spams create a plug of red blood cells

-White blood cells release thrombin when activated by platelets

thrombin catalyzes the conversion of fibrinogen to fibrin

-fibrin makes a mesh-like structure not platelets

Which hormone is incorrectly paired with the process it affects?

-parathyroid hormone: bone degradation by osteoclasts

-aldosterone: reabsorption of Na+ by kidneys

-thyroxine: production of sperm and egg

-oxytocin: breastmilk ejection

thyroxine(t4) raises metabolism

***Which type of muscle changes pupil size in response to light?

-smooth

-cardiac

-skeletal

-contractile

smooth muscle

-think about how it happens involuntarily=smooth

***The diagram below shows the female reproductive system. Select the area in which fertilization typically occurs.

uterine tubes

Release of which neurotransmitter causes the contraction of skeletal muscles?

acetylcholine

Which of the following is a long bone?

humerus

Bile serves what primary function in the digestive system?

emulsification of fats and oil

Which of the following cells produce a pigment that helps protect the skin from ultraviolet(UV) radiation?

-dendritic cells

-keratinocytes

-Merkel cells

-melanocytes

melanocytes

The tricuspid valve is found between which structures?

right atrium & right ventricle

***Which of the following are associated with osteoclast function? (Select all that apply)

-Degradation of bone matrix

-Release of calcium ions into the blood

-Promotion of mineralization

-Formation of osteocytes

-Secretion of acid

-Degradation of bone matrix

-Release of calcium ions into the blood

-Secretion of acid (osteoclasts break down bone by secreting acid)

In what specific structure do gases exchange between the lunges and the blood?

alveoli

***Which of the following would produce active immunity?

-A baby receives immunoglobins through breast feeding

-Rabies globulin is transfused to a patient after an animal bite

-Antibodies are passed from mother to fetus through placenta'

-A tetanus vaccination is administered after a high-risk injury

-A tetanus vaccination is administered after a high-risk injury

• Passive immunity (breastfeeding): The mother makes the antibodies, and the baby receives them.

• Active immunity (vaccination): The vaccine stimulates the baby's or patient's own immune system to make antibodies.

Which cardias structure is often referred to as the pacemaker?

sinoatrial node

***Which of the following processes occurs in the highlighted area of the diagram?

Osmosis of water into the blood along its concentration gradient
