Smooth muscle.

Blood vessels contain smooth muscle in their walls. Cardiac muscle is heart muscle specifically. Skeletal muscle is muscle that forms the voluntary muscles.

In the human body, the circulatory systems are made up of smooth muscle.

Option (a);

<u>EXPLANATION:</u>

The circulatory system of a body helps to transfer nutrients and oxygen from the small intestine and the lungs respectively to the cells of the body.

This reduces the waste content from the human body.

The blood vessels of the circulatory system are made up of smooth muscle tissue.

The smooth muscle cells around the blood vessels help to regulate the blood flow to the different segments of the body.

It helps to change the diameter of the arteries.

When the arteries constrict, it reduces the space for blood to flow increasing the blood pressure.

Alex is participating in a 50 meter dash. Predict the most important chemical process his muscles will rely on during this race.
natta225 [31]

Answer: The correct answer to the question is option E

BOTH ANAEROBIC RESPIRATION AND CREATININE PHOSPHATE BREAKDOWN.

Explanation: 50 meter dash is a race,a form of exercise, energy is required as well as muscle contraction and chemical processes.

Alex muscles will rely on the following chemical processes during the race;anaerobic respiration and creatine phosphate breakdown.

These chemical processes are explained below;

Aerobic respiration uses oxygen to generate energy but unlike aerobic respiration, anaerobic respiration breaks down glucose to provide energy and create adenosine triphosphate(ATP), lactic acid and ethanol.

Muscle contraction cannot take place without the supply of energy by ATP, molecules can store energy in it's phosphate form, this molecule is known as creatine phosphate,when this happens,ATP that is in excess will then transfer it's energy to creatine,this action will produce creatinine phosphate and adenosine diphosphate (ADP) and they will now be stored as reserve of energy that can be used to produce more ATP and thus energy is produced.
