The Rh factor antigen in blood determines:
postive or negative |
|
blood type |
|
universal recipient status |
|
universal donor status |
Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.
Water freezing or boiling is an example of which of the following?
heating |
|
phase transition |
|
cooling |
|
sublimation |
A substance undergoes a phase transition when it moves from one state of matter to another, for example, when water freezes or boils.
The universal recipient blood type can recieve any other blood type. Which blood type is the universal recipient?
O-negative |
|
AB-positive |
|
O |
|
AB |
Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.
Which of the following is not one of the outer planets?
Uranus |
|
Neptune |
|
Venus |
|
Jupiter |
In contrast to the solid terrestrial planets, the outer planets (Jupiter, Saturn, Uranus, and Neptune) consist of hydrogen and helium gas and water.
Which of these represents the path of blood flow through the heart?
right atrium → left ventricle → lungs → left atrium → right ventricle |
|
left atrium → right ventricle → lungs → left atrium → right ventricle |
|
left atrium → left ventricle → lungs → right atrium → right ventricle |
|
right atrium → right ventricle → lungs → left atrium → left ventricle |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
