Question and answers rated A+ 2023
What is Anatomy and Physiology? - correct answer Anatomy and physiology are
studies of how the human body works. Anatomy focuses on the structure of the body
and how it is designed, and physiology looks at how the body functions
If you're studying the body at the chemical level, what is the smallest building block? -
correct answer Atoms
What is the order of organization from Atoms to Organism? - correct answer Atom
Molecule
macromolecule
Organelle
Cell
Tissue
Organ
Organ system
Organism
What is tissue and what are the 4 basic types? - correct answer Tissues are groups of
cells that perform a common function.
The four basic tissue types in the human body are
epithelium,
muscle,
connective,
and nervous tissue,
each of which is made up of specific cell types that perform specific functions
What is the role of epithelial tissue? - correct answer covers the body surface and
lines the cavities of the body. The cells that make up epithelial tissue are specialized for
tasks such as secretion and absorption
The structure of epithelial tissue contains closely packed cells with very little matrix
(layer outside the cells). Epithelial tissue can be found as one layer or in many layers.
These cells are under constant cell division to replace dead cells that shed away.
, What is the role of muscle tissue? - correct answer Muscle tissue enables us to move
(Figure 1.3). The cells that make up muscle tissue are specialized for muscle
contraction.
What is the role of connective tissue? - correct answer Connective tissue (Figure 1.4)
offers support and protection of body organs and includes bones, tendons, blood, and
ligaments. Connective tissue cells are specialized to bind tissues together and play a
supportive role.
What is the role of nervous system tissue? - correct answer Nervous tissue (Figure
1.5) is responsible for the communication between the cells of the body by forming a
system of electrical impulses that communicate very rapidly. Nerves are like the "wiring"
of the body.
What are the three layers of the integumentary system? - correct answer Epi-Dermis
(surface)
Dermis- Contains pressure sensors, sweat glands, hair follicles
Hypodermis- Mostly fat for insulation and protection
What is the role of the skeletal system? - correct answer Serves as the framework for
the muscular system and supports the body organs. The skeletal system also provides
protection for internal organs and houses blood cells as well as stores minerals. The
skeletal system provides the framework for which the muscles attach.
What are the three types of muscle fibers? - correct answer Skeletal muscle fibers
Cardiac muscle fibers
Smooth muscle fibers
What is the role of the digestive system? - correct answer Breaks down food into
small molecules. Those molecules enter the bloodstream through the small intestine
and supply the body with nutrients
What are the 4 layers that make up the small intestine? - correct answer Serosa
mucosa
sub-mucosa
Muscularis
