What is pH of blood?

7.4

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.

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

Actin, 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.

What type of tissue is blood?

Connective

Horses Kidney

Is heart shaped

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

Myofilaments

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).
