Q1 QUESTION 1 OF 68
which body system supplies cells with oxygen and nutrients and carries away waste?(marcar x)
CORRECT ANSWER
circulatory system
RATIONALE
The circulatory system facilitates the transport of oxygen and essential nutrients to cells while simultaneously removing metabolic waste
products through its network of blood vessels and the action of the heart. This dynamic system is for maintaining homeostasis and
supporting cellular function.
Q2 QUESTION 2 OF 68
the pericardial cavity contains the:
CORRECT ANSWER
heart
RATIONALE
The pericardial cavity is a fluid-filled space that surrounds the heart, providing lubrication to reduce friction during cardiac movements.
This anatomical relationship is critical for maintaining optimal heart function and protecting it from surrounding structures.
Q3 QUESTION 3 OF 68
which layer of heart anchors it to the diaphragm?
CORRECT ANSWER
A. Endocardium
B. Mediastinal
C. Myocardium
D. Correct! Pericardium
RATIONALE
The pericardium, a fibrous sac surrounding the heart, provides structural support and anchors the heart to the diaphragm through its outer
fibrous layer, maintaining positional stability during cardiac cycles. This anchoring prevents excessive movement and promotes efficient
hemodynamics within the thoracic cavity.

, what is the purpose of the fossa ovalis in a fetus
CORRECT ANSWER
It allows fetal blood to move directly from right to left atrium, bypassing he undeveloped lungs. The fossa ovalis closes during birth
so that the lungs can receive oxygen once the baby is born.
RATIONALE
The fossa ovalis facilitates shunting of blood from the right atrium to the left atrium in fetal circulation, allowing oxygenated blood to
bypass the non-functioning lungs. Closure of this structure at birth is critical for establishing normal pulmonary circulation and
oxygenation after the infant takes its first breaths.
Q5 QUESTION 5 OF 68
