Body Systems
Which system provides support and protection? It gives the body shape.
Skeletal system
What is the smallest unit of all living things?
Cells
Describe the anatomical position (3 things I am looking for)
feet facing forward, arms at your side, thumbs facing away from the body
Fill in the blank: Body systems work together to complete the _______ necessary for life. These functions provide the items needed for the _______ of the whole organism.
Functions and survival
______ feedback loop opposes the stimulus
negative
Which system fights infection and provides fluid for cells?
The Lymphatic system
_______ is made of 2 or more types of tissues.
Organs
The dorsal body cavity encloses the _____ & ______ cavity
Cranial & Vertebral
What is the function of maintaining boundaries? provide and example.
letting some things in and keeping others out. ex: bacteria from a door handle does not penetrate the skin.
Give me one example of a negative feedback loop
- shivering to warm you up
-sweating to cool you off
Which system of the body contains glands and hormones?
The endocrine system
List the organizational level of the body
Cells > tissues > organ > organ system > organism
If someone sliced you between the eyes and directly downwards, what type of plane would that be?
Median/ midsagittal
What is the function of metabolism? and give and example
building larger molecules from small ones (anabolism) and breaking down of larger molecules into smaller ones (catabolism). ex: glucose is combined to form glycogen for energy storage
What is homeostatic regulation?
Adjustments made in the human organism to maintain a stable environment
Which system transports nutrients and gases around the body?
The circulatory system
List the 4 types of tissues our 11 body systems are made of
What is included in the ventral body cavity?
Thoracic, abdominal, and pelvic cavities
list the 5 survival needs
nutrients, oxygen, normal body temperature, water, and normal atmospheric pressure
Give me an example of a positive feedback loop
amplifies the process - labor contractions and blood clotting are both examples
What is the function of the integumentary system?
Protect the body, regulate temperature, and prevent water loss
What tissue type makes conducts electrical impulses through the brain, spinal cord, and nerves?
Nervous
What is the most proximal point of your lower extremities (legs)?
The hip
How does normal atmospheric pressure aid in survival?
provides appropriate gas exchange between lungs and environment
describe how cellular metabolism impacts homeostasis
Metabolism, is responsible for building up and breaking down cells. Cells adjust their metabolism to respond to internal and external cues, ensuring that conditions remain within a range that supports optimal function and survival
