Question 88

Classify the following as either part of systemic anatomy or regional anatomy. (Select all that apply)

Digestive system
Head
Respiratory system
Neck
Cardiovascular system
Trunk (Thorax and Abdomen)
Muscular system
Upper limbs
Endocrine system
Lower limbs
Nervous system
Reproductive system
Urinary system
Skeletal system
Integumentary system
Lymphatic system

Answer 88

Systemic Anatomy:

Digestive system
Respiratory system
Cardiovascular system
Muscular system
Endocrine system
Nervous system
Reproductive system
Urinary system
Skeletal system
Integumentary system
Lymphatic system
Regional Anatomy:
2. Head
4. Neck
6. Trunk (Thorax and Abdomen)
8. Upper limbs
10. Lower limbs

Question 89

Explain the difference between systemic anatomy and regional anatomy. Provide one example of each type of study.

Answer 89

Systemic anatomy involves studying individual organ systems across the entire body, focusing on how organs within a system function together. For example, studying the digestive system would be systemic anatomy.
Regional anatomy, on the other hand, studies all structures (bones, muscles, nerves, blood vessels) within a specific body region. For instance, studying the lower limbs would be an example of regional anatomy.

Question 90

Which of the following correctly describes the hierarchical levels of organization in the human body from the simplest to the most complex?
a) Tissues → Cells → Organs → Organ Systems → Organism
b) Cells → Tissues → Organs → Organ Systems → Organism
c) Cells → Organs → Tissues → Organ Systems → Organism
d) Tissues → Organs → Organ Systems → Cells → Organism

Answer 90

Answer: b) Cells → Tissues → Organs → Organ Systems → Organism
Rationale: This is the correct hierarchical order of biological organization, starting from the smallest functional unit (cells) and progressing to the complete organism.

Question 91

Explain how cells, tissues, organs, and organ systems are interrelated, and provide one example of each level.

Answer 91

Cells are the smallest units of life. Similar cells combine to form tissues, such as muscle tissue. Multiple types of tissues work together to form organs, like the heart, which is made up of muscle, nervous, connective, and epithelial tissues. Organ systems, like the digestive system, consist of organs working together to perform a specific task. Finally, the organism is the complete living entity.

Question 92

Which of the following is the primary function of the digestive system?
a) Circulating nutrients throughout the body
b) Breaking down and absorbing nutrients necessary for growth and maintenance
c) Filtering and removing waste products from the body
d) Producing hormones to regulate metabolism

Answer 92

b) Breaking down and absorbing nutrients necessary for growth and maintenance
Rationale: The digestive system’s main role is to break down food and absorb nutrients that are essential for the body’s growth and maintenance.

Question 93

The urinary system is involved in filtering out _________, _________, and excess _________ or _________ from the circulatory system, which helps maintain the body’s _________ and _________ balance.

Answer 93

Answers:

cellular wastes
toxins

Question 96

Fill-in-the-Blank
The peripheral nervous system includes ____________ pairs of cranial nerves and ____________ pairs of spinal nerves, which relay ____________ signals through the body and are involved in directing ____________ and ____________.

Answer 96

Answer:
The peripheral nervous system includes 12 pairs of cranial nerves and 31 pairs of spinal nerves, which relay electrical signals through the body and are involved in directing behavior and movement.
