Exploring Endocrine, Circulatory, and Respiratory Systems

The assignment is to complete lab reports on the endocrine, cardiovascular, and respiratory systems. The student will observe diagrams of these systems and fill out tables with information about each organ or part, including its name, function, and any hormones produced or secreted.

Assignment: SCIE207 Phase 4 Lab Report
Title: Exploring Endocrine, Circulatory, and Respiratory Systems
Instructions: Your lab report will consist of the completed tables. Label each component of the
endocrine, cardiovascular (circulatory), and respiratory systems and their functions in the
following tables.
When your lab report is complete, submit this document to your instructor in your
assignment box.
Endocrine System: Observe the diagram showing the major organs of the endocrine system.
Using the textbook and Virtual Library resources, fill in the following table:
Endocrine System
Number Name of the Organ or Part Hormone(s) Produced or Secreted
1 Parathyroid Glands Parathyroid hormone
2 Thyroid Gland Thyroxine, calcitonin
3 Pineal Gland Melatonin
4
Hypothalamus Produces ADH and oxytocin, regulatory hormones for
the anterior pituitary.
Produces and secretes TRH, Dopamine, GHRH,
Somatostatin, Gonadotropin.
5 Pituitary Gland Anterior: Produces and secretes ACTH, TSH, GH,
FSH, LH, MSH Posterior: Secretes Oxytocin and ADH
6 Thymus Thymosins
7 Heart Atrial natriuretic peptide, brain natriuretic peptide
8 Stomach Ghrelin, Gastrin, Histamine, Neuropeptide Y,
Endothelin
9 Kidney Erythropoietin, Renin, Calcitriol
10 Small Intestine
(duodenum)
Secretin, cholecystokinin

11
Liver Insulin-like Growth factor 1 (IGF-1), Angiotensinogen,
Thrombopoietin
12
Adrenal Glands Medulla: epinephrine, norepinephrine.
Cortex: glucocorticoids (cortisol), aldosterone,
testosterone
13 Pancreas Insulin, glucagon
14 Testes Androgens, testosterone
15 Uterus Prolactin and Relaxin, when pregnant
16 Ovary Estrogens, progesterone
Cardiovascular System: Observe the diagram showing the major structures of the
cardiovascular (circulatory) system. Using the textbook and Virtual Library resources, fill in the
following table:
Cardiovascular System
Number Name of the Structure Major Function
1 Carotid arteries Delivers blood to the head and brain
2 Jugular veins Carries blood from the head to the heart
3 Superior vena cava Carries blood from the upper body back to
heart
4 Pulmonary veins Carries oxygenated blood from the lungs to
the heart
5 Aorta Delivers blood to the body tissue
6 Pulmonary arteries Delivers oxygen-poor blood to the lungs
7 Coronary arteries Delivers blood to the heart muscle cells
8 Inferior vena cava Carries blood from the lower body back to
heart
9 Renal vein Carries blood from the kidney to the heart

10 Iliac vein Delivers blood from the pelvic organs and
abdominal wall to the heart
11 Radial vein Carries blood from the hand to the heart
12 Renal artery Delivers blood to the kidneys
13 Iliac artery Delivers blood to the pelvic organs and
abdominal wall
14 Radial artery Delivers blood to the hands
15 Femoral vein Carries blood from the thigh and inner knee
to the heart
16 Femoral artery Delivers blood from the thigh and inner
knee
Respiratory System: Observe the diagram showing the major organs and structures of the
respiratory system. Using the textbook and Virtual Library resources, fill in the following table:
Respiratory System
Number Name of the Organ or Structure Major Function
1 Sinuses Cavities in skull; lightens head, warms
and moistens air
2 Nasal cavity Produces mucus; filters, warms and
moistens air; olfcation
3 Pharynx Passageway for air and food
4 Epiglottis Covers larynx during swallowing
5 Larynx Air passageway; prevents food and drink
from entering lower respiratory system,
produces voice
6 Lungs Contains alveoli and air passageways,
allows exchange of oxygen and carbon
dioxide between atmosphere and blood
7 Trachea Connects larynx with bronchi leading to
lungs, conducts air to and from bronchi
8 Bronchi Two branches of trachea that conduct air
