A11: Sweating to reduce body temperature when overheated.
Q12: What is a positive feedback mechanism?
A12: A system that intensifies a change (e.g., blood clotting, childbirth contractions).

A20: Stomach, liver, intestines, pancreas, spleen, kidneys.
O
Q21: What organs are found in the pelvic cavity?
A21: Bladder, reproductive organs, rectum.
FD
Q22: What are serous membranes?
A22: Thin membranes lining cavities and covering organs.
Q23: Name the serous membrane covering the lungs.
A23: Pleura.
O
Q24: Name the serous membrane covering the heart.

Q28: What does superior mean in anatomical terms?
A28: Toward the head or upper part of the body.
,Q29: What does inferior mean?
A29: Away from the head; toward the lower part of the body.
Q30: What does anterior (ventral) mean?
A30: Toward the front of the body.
Q31: What does posterior (dorsal) mean?
A31: Toward the back of the body.
Q32: What does medial mean?
A32: Toward the midline of the body.
Q33: What does lateral mean?
A33: Away from the midline of the body.
PR
Q34: What does proximal mean?
A34: Closer to the origin of a body part or point of attachment.
Q35: What does distal mean?
A35: Farther from the origin of a body part or point of attachment.
O
Q36: What does superficial mean?
A36: Toward or at the body surface.
FD
Q37: What does deep mean?
A37: Away from the body surface; more internal.
Q38: What are the three major body planes?
A38: Sagittal, frontal, transverse.
O
Q39: What is a sagittal plane?
A39: Divides the body into right and left parts.
C
Q40: What is a midsagittal plane?
A40: Divides the body into equal right and left halves.
Q41: What is a frontal (coronal) plane?
A41: Divides the body into anterior and posterior sections.
Q42: What is a transverse (horizontal) plane?
A42: Divides the body into superior and inferior parts.
Q43: What is the smallest unit of life?
A43: The cell.
, Q44: What is metabolism?
A44: All chemical reactions that occur within the body.
Q45: What is catabolism?
A45: The breakdown of complex molecules into simpler ones, releasing energy.
Q46: What is anabolism?
A46: The building of complex molecules from simpler ones, requiring energy.
Q47: What are the survival needs of the human body?
A47: Nutrients, oxygen, water, normal body temperature, appropriate atmospheric pressure.
Q48: What is meant by physiology being “integrative”?
A48: Body systems work together; one system affects others.
PR
Q49: What is the difference between gross and microscopic anatomy?
A49: Gross anatomy studies large structures visible to the naked eye; microscopic anatomy
studies cells and tissues.
