Q

Organs in the digestive system and the functions

A
  1. The MOUTH contains glands that secrete mucus, saliva, and enzymes to start breaking down food (digestive starts in mouth)
  2. The TOUNGE moves food to back of throat
  3. The food travels past the PHARYNX through the ESOPHAGUS (tube that food goes through from peristalsis - rhythmic contractions that smooths muscles to STOMACH
  4. The EPIGLOTTIS is a flap attached to root of tongue and entrance to LARYNX (voice box), it flips between esophagus and trachea, depending on eating or breathing
  5. STOMACH churns food and mixes. with digestive juices and enzymes
  6. Nutrients move to SMALL INTESTINE, the nutrients are absorbed
  7. Waste/food moves to LARGE INTESTINE where water is absorbed
  8. Solid waste stored in rectum and exit anus

Not part of system but part of system:
- Liver secreates bile and breaks down fat
- Gallbladder stores bile
- Pancreas secreates its juice, insulin, and enzymes into intestine

Q

What are veins?

A

Carly deoxygenated blood back to heart, blood flowing through veins is at lower pressure than in arteries (has thinner walls), contains valves so blood does not flow backwards.

Q

Organs and functions in the excretory system?

A
  1. Blood flows through KIDNEYS, water removed by NEPHRONS
  2. Wastes form URINE
  3. Urine moves out of kidneys down the UTERUS and the URINARY BLADDER where stored until eliminated, through the URETHA
  • Skin is also part of system as it excretes water, salts, and urea in sweat

Q

Organs and functions in the respiratory system?

A
  1. During breath, air passes through NOSE/MOUTH
  2. Then through PHARYNX
  3. Past LARYNX (voice box)
  4. Into TRACHEA (tube ringed with cartilage)
  5. Into BRONCHI
  6. Into smaller BRONCHIOLES
  7. Then ALVEOLI (tiny air sacks - GAS EXCHANGE), which are surrounded with CAPILLARIES (thin-walled blood vessels)
  • Into diaphragm at end
  • CO2 is picked up from cells and travels fro blood stream across alveoli
  • Oxygen travels from alveoli through capillaries into blood to cells in body

Q

Function on skeletal system?

A

Skeletal system
- Contains bones and cartilage
- Supports and protects body
- Allows movement

17
Q

Function on muscular system?

A
  • Contains 3 types of muscle, tendons, and ligament’s
  • Moves body
18
Q

Female and Male reproductive system organs and functions?

A

Female
- Contains ovaries (stored eggs), Fallopian tubes (links to ovaries and uterus), uterus (where babies develop), and vagina (opening in females)

Male
- Contains testes (produce sperm), epididymis (stores sperm), vas deferens (connecting tube), urethra (travels through penis)

19
Q

What is fertilization?

A

The process of combining the male gamete, or sperm, with the female gamete, or ovum.

20
Q

Breathing and exhaling

A

When you inhale your rib cage rises, and your diaphragm contracts and moves downward, which increases your chest cavity (increase in volume of cavity causes decrease in internal air pressure)

Air rushes in your lungs to equalize pressure

When you exhale your ride cage lowers, diaphragm relaxes and moves up, decreasing size of chest cavity and increases the internal air pressure

21
Q

Flow chart of Excretory system (top to bottom of labeling diagram)

A
  1. Aorta
  2. Kidney
  3. Vena Cava
  4. Ureters
  5. Bladder
  6. Urethra
22
Q

Flow chart of digestive system (labeling diagram)

A
  1. Mouth
  2. Past pharnayx
  3. Esophagus
  4. Stomach
  5. Small intestine
  6. Large intestine
  7. Rectum
  8. Anus

Know the liver, gallbladder, appendix, pancreas

23
Q

Flow chart of Circulatory system

A
  1. Right atrium
  2. Tricuspid
  3. Right ventricle
  4. Pulmonary valve
  5. Pulmonary artery
  6. Lungs
  7. Pulmonary vein
  8. Left atrium
  9. Bicuspid
  10. Left ventricle
  11. Aortic valve
  12. Aortia
  13. Body
  14. Inferior and superior vena cava
24
Q

Flow chart of respiratory system

A
  1. Nose/mouth
  2. Pharynx
  3. Larynx
  4. Trachea
  5. Bronchi
  6. Broncioles
  7. Alveoli
  8. Capillaries
25
Q

Function of dermis and epidermis

A

They are both part of the integumentary system

Epidermis
Outer layer made up of epithelial tissue, prevents bacteria and viruses from entering body, makes vitamin D when exposed to sun

Dermis
Inner layer of connective tissue, nervous, and muscle, provides structure and support, releases excess heat, secreates sweat to cool body, has layer of fat, contains nerves sensitive to pain, pressure, heat, cold, and sends info to brain, muscles produce goosebumps (hair thickens for warmth when cold to make us look big when scared)

26
Q

Arteries vs veins (4)

A

Arteries are thicker walled and veins are thinner

Arteries carry oxygenated blood and veins carry deoxygenated blood

Arteries do not have valves and veins do have valves

Arteries carry blood towards heart and veins carry blood away

ONLY EXCEPTION is pulmonary artery carries deoxygenated blood

27
Q

Flow chart of frog

A
  1. Tongue
  2. Mouth
  3. Gullet

  5. Stomach
  6. Intestines
  7. Cloaca (opening material exists)
28
Q

3 things learned from documentary

A
  1. Babies have a hole in skull when born

A
  • Contains glands, pancreas, ovaries and testes
  • Organs secreate hormones to control metabolism, growth and development
31
Q

What is the lymphatic system?

A
  • Contains white blood cells, thymus, spleen, lymph nodes, lymph vessels
  • Protects body from disease
  • Absorbs and transports fats
32
Q

Function and about lungs

A
  • Organ that allows to breathe in oxygen and out carbon dioxide
  • Humans have two lung cavity in chest area, which is enclosed by ribs, chest muscles, and DIAPHRAGM
  • Lungs are separated by thin layer of fluid (pleura) which protects lungs and reduces friction
33
Q

What are tissues?

A

Group of cells that function together to perform specialized tasks

34
Q

Function of respiratory organ system?

A

All cells in the body need oxygen to produce energy for cellular respiration, growth and reproduction

35
Q

Function of excretory organ system?

A

Filters waste products from body and maintains proper levels of water and electrolytes

36
Q

Function of integumentary system?

A

Made up of skin and accessory structures (nails, antlers, hair, etc)

37
Q

What is homeostasis and how your body contains it

A

It is a steady state. There is an acceptable range of physical and chemical condition with body cells tissue and organs can operate efficiently. Maintain stable internal environment
