Just to add onto jxxu's questions since I got the renal half of the event. wheres all the love for kidneys my dudes
1. List these nephron components in order: descending limb, bowman's capsule, distal convoluted tube, proximal convoluted tube, ascending limb, collecting duct
2. List these kidney arteries in order: arcuate artery, renal artery, interlobar artery, cortical radiate artery, afferent arteriole, efferent arteriole, segmental artery
3. What is the name of the capillaries in bowman's capsule?
5. What's the name of the capillaries around the loop of henle?
6. What is the muscle that controls contraction in the bladder?

1. 50%

2. They initiate V(D)J recombination, which causes much greater diversity in the range of defenses against harmful microbes. It is a necessary step in the maturation of pre T cells.

3. left brachiocephalic vein

4. centroblast: enlargened, activated B cell
centrocyte: B cell with a dent in the nucleus

1. Bowman's capsule, PCT, descending limb, ascending limb (DL and AL make up loop of Henle), PCT, collecting duct
2. renal artery, segmental artery, arcuate artery, cortical radiate artery, afferent arteriole, efferent arteriole, interlobar artery,
3. Glomerulus
4. peritubular capillaries
5. detrusor muscle, activated by micturition reflex

The answers to my questions were correct for the most part, but be careful and check number 1.

This is a dihybrid cross -- there is a 50% or 1/2 chance of the children being type AB and 50% chance of them being type A(O). Crossing the alleles for Rh factor, we see that 50% (1/2) of the children will have a genotype of Dd (heterozygous, meaning that they have the Rh factor) while 50% (1/2) are homozygous recessive (dd, meaning that they are Rh negative). 1/2 AO * 1/2 Rh+ = 1/4 type A blood and Rh positive. Therefore, the correct answer should be 25%.

Ok, nice to know.

1. Describe 3 symptoms of Hodgkin's Lymphoma.

2. What is lymph called prior to being collected by lymphatic vessels?

3. State what happens in the red pulp of the spleen.

3. State what happens in the red pulp of the spleen.
1. Drowsiness, fever, and swollen lymph nodes.
2. Extracellular fluid.
3. Blood is being filtered of old/damaged red blood cells.

1. Nice!
2. Great, interstitial fluid also works
3. Nice
Looks good, go ahead!

1. What induces movement of lymph fluid throughout the body?

2. What does GFR stand for? Describe it.

3. During the cardiac cycle, which phase has the lowest ventricular volume?

1. Lymph does not have a "pump" (as the cardiovascular system has the heart), so the movement of lymph depends on the motion of muscles and joints beside it.

2. GFR stands for glomerular filtration rate. It approximates the volume of blood that flows through the glomeruli of the kidney in mL/min.

3. Diastole

Some excretory system questions:

1. Name the layers of the kidney from outermost to innermost layer.

2. The specialized cells of the Bowman's capsule are known as __________.

3. Which part of the nephron has the greatest osmolarity?

4. Why are women at a higher risk of developing a UTI than men?

5. List and explain the three (3) main stages in the formation of urine.
