Urine exits the kidneys through the: Bladder Urethra Ureters Collecting ducts Filtration of blood in the kidney nephron begins in the: Loop of Henle Proximal convoluted tubule Bowman's Capsule Distal convoluted tubule Most aquatic animals secrete nitrogenous wastes in the form of ____, but land animals convert this into other Chemicals that are less toxic. Urea Uric acid Ammonia Proteins When fats are digested: their breakdown products are absorbed into the bloodstream from the vill of the small intestine their digestion begins in the stomach, where they are broken down by HCI and pepsinogen their breakdown products are absorbed by the liver, where they are stored as glycogen their breakdown products are absorbed into the lymphatic system from the villi of the small intestine Which of the following options correctly lists the structures in the kidney nephron in the order in which fluid flows through them? glomerulus, Bowman's capsule, proximal tubule, loop of Henle, distal tubule glomerulus, proximal tubule, distal tubule, Bowman's capsule, loop of Henle proximal tubule, Bowman's capsule, loop of Henle, distal tubule, glomerulus Bowman's capsule, proximal tubule, loop of Henle, distal tubule, glomerulus What is the function of antidiuretic hormone (ADH)? to stimulate sodium reabsorption to counter the effects of alcohol consumption to increase urination to increase water reabsorption All of the following are tropic hormones except: FSH oxytocin ACTH TSH The chemical that transmits an action potential (nerve signal) across a synapse is called a(s): ion pump neurotransmitter electron transporter hormone The intense uterine contractions of labor are caused by the hormone: FSH estrogen progesterone oxytocin A hormone produced by the stomach that causes the feeling of being hungry is called: gastrin ghrelin leptin PYY During the process of blood clotting in an injured vessel, all of the following are true except: platelets are attracted to exposed connective tissue at the injury site clotting factors are released, setting off a cascade of reactions that eventually produce fibrin platelets eventually contract, pulling the edges of the wound back together strands of fibrinogen surround the platelets, helping to close the wound

Answer 1

Answer37]=

The urine exists through the kidney through

c] Ureters

explanation= The urine is formed by nephrons .

The nephrons are structural & functionlal unit of kidney .

Then urine flows from nephron through a system of converging tubules called as collecting ducts .

The collecting duct joins to form minor calyces ,then major calyces ,which ultimately joins the pelvis or renal sinus.

Urine flows from renal pelvis into ureters

Then ureters carry the urine from kidney to urinary bladder.

urinary bladder stores the urine temporary then passes to the urethra

urethra expels the urine through the body .

$\therefore$ ureters is the correct answer.

38] Answer

Filteration of the blood in the kidney nephron begins in

c] Bowmans capsule

explanation= the formation of urine begins with the filteration process.

fluid & small solutes are forced under pressure to flow from the glomerulus in the capsular space of the glomerular capsule .

Bowmans capsule is the filteration unit of glomerulus .& has tiny slits in which filterate may pass into the nephron

blood is filtered in the bowmans capsule

Hence bowmans capsule is correct option

39] most aquatic animals secrete nitrogenous waste in the form of ammonia but land animals convert this into less toxic chemicals .

c] Ammonia

explanation= the nitrogenous waste is produced in case aquatic animals in the form of ammonia .

for the elimination of ammonia it requires more amount of water that is about 300 to 500 ml of water per gram of ammonia .

ammonia is highly toxic.

in case of land animals this ammonia is combine with carbon dioxide to form less toxic chemical i.e. urea

it require less amount i.e. 50 ml of water per gram for its elimination
