Human Body Systems - M/C - 2
a
Which process must first take place in order for the proteins in foods to be used by body cells? a. digestion b. storage c. synthesis d. excretion
a
The activity of all human body systems is coordinated by a. the secretion of hormones and the nervous system b. the interaction of nerve impulses with the excretory system c. the movement of digested food by the circulatory system d. the secretion of hormones and the circulatory system
d
The breathing rate, heart rate, and blood hormone levels of an individual would directly provide information about that individual's a. cellular organization b. nutrition c. inheritance d. metabolic activity
a
The function of which cell part is most similar to that of the human excretory system? a. cell membrane b. nucleus c. ribosomes d. mitochondrion
c
The major role of carbohydrates in the human diet is to a. form the membrane that surround mitochondria b. act as a catalyst for cellular reactions c. supply energy for the body d. provide building blocks for amino acids
c
Which body system is correctly paired with its function? a. excretory - produces antibodies to fight disease - causing organisms b. digestive - produces hormones for storage and insulation c. circulatory - transports materials for energy release in body cells d. respiratory - collects waste material for digestion
a
Which change is an example of a response to a stimulus? a. the pupil of an eye decreases in size in bright light b. A leaf absorbs sunlight in the morning c. The water level of a pond rises on a rainy day d. A dead tree decays after many years
c
A similarity between the Nervous, Circulatory, Digestive, Muscular, Reproduction system is a. are made of cells that are identical in structure and function b. contain organs that work independently from other organs in that system c. work together to maintain a stable internal environment d. are separate and do not interact with other body systems
c
A similarity between the nervous system and the hormone-secreting system in humans is that they both a. are composed of the same type of cells b. are composed of many glands c. help to maintain homeostasis d. secrete chemicals directly into the blood
a
During periods of vigorous physical activity, a person's breathing and heart rate increases. This enables the cells of the body to perform more efficiently because it helps the cells to a. remove waste products faster b. store excess glucose in muscles c. reduce the amount of ATP produced d. convert more oxygen to glucose
b
If body temperature is too high, some blood vessels increase in size and sweat glands will excrete sweat, resulting in a lower body temperature. These changes are an example of a. a learned behavior b. a feedback mechanism c. an inherited disorder d. genetic mutations
c
In the human body, oxygen is absorbed by the lungs and nutrients are absorbed by the small intestine. In a single-celled organism, this absorption directly involves the a. nucleus b. chloroplasts c. cell membrane d. chromosomes
c
Inhaling carbon monoxide reduces the ability of red blood cells to carry oxygen. This can lead to brain damage. Which three systems of the body interact in this situation a. digestive, respiratory and circulatory b. immune, circulatory and digestive c. respiratory, circulatory and nervous d. excretory, nervous and respiratory
a
Organisms remove metabolic cellular wastes by the process of a. excretion b. absorption c. coordination d. digestion
c
Single-celled organisms are able to maintain internal stability because they a. have multiple organ systems b. work with other cells c. contain structures that perform life functions d. carry out photosynthesis to produce food
a
Which two systems are most directly involved in providing molecules needed for the synthesis of fats in human cells? a. digestive and circulatory b. excretory and digestive c. immune and muscular d. reproductive and circulatory
