Answer from: miko96

External respiration : CO2 diffuses into the blood stream.

Explanation:

Respiration may be defined as the process of exchange of gases between the external atmosphere, alveoli and the internal tissue. Two main important types of respiration are external respiration and internal respiration.

The internal respiration explains the diffusion and exchange of gases between the tissue. The diffusion of the carbon dioxide in the blood stream is not the external respiration because in external respiration the gases exchange occur in the lungs across the respiratory membrane. The carbon dioxide diffusion in the blood stream is internal respiration.

Thus, the correct answer is option (3).

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force. eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/
