What is the pH of blood?

74

Blood makes up ___A_____ % of body weight and is pH ___B____. It is red in color due to the ________C_____ content of eryhtrocytes. The higher the degree of ________D_______ saturation of hemoglobin, the brighter the color. One of the main functions of blood is to ____E_________ substances around the body, including oxygen, carbon dioxide, nutrients, and waste products. Blood is also the transport medium for the secretiont of endocrine glands (_____F__________) and distributes ____G_____ from the muscles and liver. The blood also contains luecocytes, which are involved in body _____H______. If the vascular system is damaged in any way, it will be repaired by the _____I______ mechanism. Blood osmotic pressure is maintained mainly by the plasma proetin _______J_______.

A: 5-10 B: 7.4 C: hemoglobin D: oxygen E: transport F: hormones G: heat H: defense I: clotting J: albumin

At the A , fluid from the bloodstream is filtered through the blood vessel wall into the B capsule. This fluid is called C of plasma (or glomerular filtrate). It is very similar to blood plasma except that it does not contain blood cells or the larger plasma D . The filtrate then moves along the nephron. As it progresses, certain portions of its constituents are taken back into the bloodstream via the capillaries surrounding the nephron. This is called E reabsorption. Only the constituents necessary to the body are reabsorbed such as glucose, amino acids, and a few others to maintain optimal conditions in the F , such as sodium and water. Metabolic waste products, such as G and excess amounts of water, sodium, etc., remain in the nephron and pass into the H ducts where they move down the ureter into the bladder as urine.

A: glomerulus B: Bowman's C: ultra filtrate D: proteins E: selective F: ECF G: urea H: collective

Match the letters to the component of blood they are indicating. (ignore D on pic)

A: plasma B: white blood cells and platelets C: red blood cells

Which of the following are two primary proteins involved in skeletal muscle contraction and relaxation?

Actin and Myosin

During a skeletal muscle contraction, a neurotransmitter is released down the T-tubules in the myofibrils stimulating a release of_____________ from the ____________, which causes the ____________on the _____________molecule to move, allowing the ______________ protein to bind and rotate ___________ degrees.

Ca; SR; tropomyosin; actin; myosin; 90

What type of tissue is blood?

Connective tissue

This part of muscle are the smallest units and are what give skeletal muscle its striated appearance.

Myofilament

The semitendinosus muscle is associated with which portion of the skeletal system?

Pelvic

The somatic nervous system regulates the activity of:

Skeletal muscle

A muscle can be name based on the number of origins it has. For example, the triceps brachii muscle has Three origins and inserts on the olecranon process of the ulna bone.

Three

For skeletal muscle, the neuromuscular junction is located on the surface of the muscle fiber (one for each muscle fiber).

True

Which of the following is NOT a function of blood?

act as a medium for nerve impulses to travel across

Match the description to the correct definition: the cup-shaped subdivisions of the ureter within the kidney

calyces

What makes blood red?

hemoglobin content of erythrocytes

Match the description to the correct definition: the blood vessel that arrises directly from the aorta and supplies the kidney

renal artery

Match the description to the correct definition: the fibrous connective tissue outer membrane of the kidney, which is protective

renal capsule

Match the description to the correct definition: the outer layer of the kidney where the renal corpuscles are found

renal cortex

Match the description to the correct definition: the area where the collecting ducts merge

renal crest

Match the description to the correct definition: the "dent" in the kidney where the ureter and blood supply is attached

renal hills

Match the description to the correct definition: the inner region of the kidney where the loops of Henle are found

renal medulla

Match the description to the correct definition: the collecting ducts empty into this area

renal pelvis

Match the description to the correct definition: the cone-shaped masses that form the renal medulla

renal pyramids

Match the description to the correct definition: the duct that transports urine from the renal pelvis to the urinary bladder

ureter
