Answer:

pre-

Explanation:

The prefix pre-, which means “before,” appears in numerous English vocabulary words, for example: predict, prevent, and prefix! An easy way to remember that the prefix pre- means “before” is through the word prevent, for when you come “before” something else to stop it from happening, you prevent it.

Blood PC02 may be measured by:

Vikentia [17]

Blood PC02 may be measured by using direct spectrophotometer

Explanation:

Blood gas analysis or arterial blood gas (ABG) test is done to determine blood pH and the amount of oxygen and carbon dioxide dissolved in arterial blood.

Blood PCO2 is the partial pressure of carbon dioxide dissolved in the arterial blood.

ABG or oximetry test is done by using direct spectrophotometry in a spectrophotometer and gas analysis is done by calorimetric methods. Spectrophotmetry is highly used in Medicine to perform quantitative analysis of blood and its composition. The spectrophotometer measures the light intensity or wavelengths absorbed by the sample solution.

Blood PCO2 reflects the degree of exchange gases in and out of the lungs. An increase in PCO2 levels indicates respiratory illnesses like obstructive lung diseases or pulmonary edema; while a decrease indicates conditions like hypoxia, pulmonary embolism, hyperventilation etc.

Which two other systems of the body is the lymphatic system most involved with? Check all that apply. circulatory system immune

sp2606 [1]

Answer:

The answers are circulatory system and immune system.

Explanation:

In order to know more about the answer, it is best to learn what a lymphatic system is.

Lymphatic System- This is also known as "lymphoid system." It functions as a part of the body's circulatory and immune system. It consists of lymphatic vessels, lymphatic organs and the lymph.

Lymphatic Vessels- These are thin-walled vessels that carry the lymphatic capillaries. The lymphatic organs include the tonsils, adenoid, spleen and thymus. 

The Function of Lymphatic Vessel

- It functions to transport the "lymph," a clear, colorless fluid which contains the white blood cells (these are also called leukocytes).This transportation function explains the lymphatic system being involved with the circulatory system in the body.

Circulatory System- This is the system in the body is responsible for blood flow, oxygen, nutrients and hormones. It also involves removing unwanted things, such as waste products in the body.

The Function of the Spleen

The spleen is one of the lymphatic organs that has an important role. Once it detects an invader in the body's blood such as virus or bacteria, it starts producing white blood cells. These are also known as "leukocytes."

The white blood cells help the body fight infection and other foreign invaders. This clearly explains the lymphatic system being involved with the immune system in the body.
