Body Cavities +organs

spleen

Abdominal cavity: blood maintance. acts like a filter for blood, helps fight bacteria

ureter

abdominopelvic cavity: carries urine from kidney to urinary bladder

ovary

abdominopelvic cavity: *only female* produce eggs for fertilization and they produce the reproductive hormones.

Cerebrum

the upper part of the cranial cavity: largest part, divided into by right and left hemisphere then divided into 4 regions. Controls senses, thoughts, and movements.

heart

thoracic Cavity:pumps blood throughout the body supplying oxygen and nutrients to the tissues.

ventral cavity

thoracic cavity- abdominopelvic cavity- abdominal cavity + pelvic cavity

Lungs

thoracic cavity: gas exchange- oxygen in blood Co2 leaving blood. "breathing oxygen enter through lungs as part of the air that we breathe.

large intestine

Abdominal Cavity: Store waste and water resorb. Converting food into feces, and reclaiming water from feces

pancreas

Abdominal cavity: helps digestion(secretes enzymes into small intestine and regulates blood sugar

vas deferens

Abdominopelvic cavity: *male only* transport mature sperm cells to the urethra. The tube that carries urine or sperm to outside the body

uterus

Abdominopelvic cavity: nurturing the fertilized ovum- support a pregnancy womb.

pituitary gland

Cranial Cavity: "master gland" produces critical hormones which are chemical substances that control various bodily functions.

amygdala

Cranial Cavity: 2 per person, responsible for emotions, survival, and memory

cerebellum

Cranial Cavity: receives information from the sensory system then regulates muscle movement(motor movements)-- posture, balance, coordination, and speech.

medulla(brainstem)

Cranial Cavity: regulate breathing, heart and blood vessel(vital)(involuntary reflex)

Brain

Cranial Cavity: regulate the functions of CNS and integrating the functions of the body as a whole.

Thoracic Cavity

Organs in the thoracic cavity include the heart and lungs.

Cranial Cavity

Part of the dorsal cavity; the cranial cavity is formed by the skull and contains the brain.

Spinal Cavity

Part of the dorsal cavity; the spinal cavity is formed by the backbone (spine) and contains the spinal cord.

mediastinum membrane

Region in the thoracic cavity between the lungs, seperating the thorax into 2 compartments that contain the right and left lungs. In it is the heart, esophagus, trachea,and thymus

Pleural membrane

Serous membranes that line the thoracic cavity.

pericardial membrane

Serous membranes that surround the heart.

Trachea(wind pipe)

Thoracic Cavity: air flow to and from the lungs for respiration

Esophagus

Thoracic Cavity: connects the throat to the stomach(passway) conduit for food and liquids that have been swallowed into the pharynx to reach the stomach

thymus gland

Thoracic cavity: vital role in training and development of T-Cells-- help immune system

Spinal Cord

Vertebral Cavity: connects a large part of the peripheral nervous system to the brain. Information reaching the spinal cord through sensory neurons are transmitted up into the brain.

small intestine

abdominal cavity: Most digestion happens here.90% of the digestion and absorpotion occur

stomach

abdominal cavity: Where digestion begins. Secretes acid and enzymes that digest food.

kidney

abdominal cavity: blood pressure, and water. filter blood to produce urine, composed of waste of extra fluid

liver

abdominal cavity: largest organ, productions of Bio(fat)-store sugars

adrenal gland

abdominal cavity: produces hormones that help the body control blood sugar, burn protein,react to stressor and regulate blood pressure. (fight &flight)

vagina

abdominopelvic cavity: a conduit for menstral from the uterus sperm will enter, birth conal

cervix

abdominopelvic cavity: barrier, tissue will dilate. allow flow of menstrual blood from uterus into the vagina, and direct the sprem into uterus during intercourse.

urinary bladder

abdominopelvic cavity: bladder stores urine, allowing urination to be infrequent and voluntary

seminal vesicle

abdominopelvic cavity: fluid will contain key components(fructose) sugar that is produced to provide energy for swimming sperm cells(keep sperm alive)

Bulbourethral/cowpers gland

abdominopelvic cavity: produce a mucous-like fluid(pre-ejaculate) the liquid neutralizes residual acidity in urehtra

Fallopian tube

abdominopelvic cavity: transport sperm toward the egg then allow passage of fertilized egg back to the uterus for implantation.

urethra

abdominopelvic cavity: tube that carries urine from bladder to outside of body. males=reproductive +urinary females= only urinary

prostate gland

adominopelvic cavity:secrete prostate fluid(componet of semen) Nurish and protect sperm. *Mioses* *male only*

Adominopelvic

consists of the abdominal cavity and the pelvic cavity. It contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, and most of the small and large intestines. It also contains the urinary bladder and internal reproductive organs.

dorsal body cavity

encloses the brain and spinal cord. cranial + spinal cavity

abdominal cavity

include the stomach, liver, gallbladder, spleen, pancreas, small intestine, kidneys, large intestine, and adrenal glands.
