Veins receive blood from the capillaries after gas exchange takes place.
____ are the smallest, most fragile blood vessels
Capillaries are the smallest, most fragile blood vessels. They are involved in the exchange of gases, nutrients, and waste products between the blood and the tissues.
Tiny air sacs where exchange of gasses occur are
The tiny air sacs where the exchange of gases occurs are called alveoli. They are found at the very end of the respiratory tree in the lungs and are crucial for the process of oxygen entering the bloodstream and carbon dioxide being expelled from the body.
Give simple answer
Alveoli.
____ is a balloon-type, bulging of a blood vessel
Aneurysm.
____ refers to the pressure in the arteries when the heart is at rest, between bears.
Diastolic pressure.
Loss of blood to the brain caused by a ruptured vessel is called
A hemorrhagic stroke.
_ Refers to the pressure in the arteries when the heart beats
Systolic pressure.
What is a basic unit of a muscle
The basic unit of a muscle is the sarcomere.
Wrong
I apologize for the misunderstanding. In the context of the cellular structure, the basic unit of a muscle is a muscle fiber, also known as a myocyte. However, if referring to the functional contractile unit within a muscle fiber, then the term "sarcomere" would be correct.
Slow-twitch muscles fibers are used when:
Slow-twitch muscle fibers, also known as type I fibers, are used during aerobic activities that require endurance and sustained effort, such as long-distance running, cycling, swimming, and any prolonged, steady-state exercise. They are efficient at using oxygen to generate more fuel (ATP) for continuous, extended muscle contractions over a long time. They resist fatigue better than fast-twitch fibers.
Simple answer
Slow-twitch muscle fibers are used during endurance activities.
___ is the sugar that is found in blood and used as the body’s main source.
Glucose.
The type of diabetes that occurs when the body’s immune system destroys the cells in the pancreas is called
Type 1 diabetes.
The organ that produces hormones such as insulin in order to break down and use food is
