Answer

To determine which statement is incorrect, we will analyze each option provided in the question step by step.

### Step 1: Analyze the first statement
**Statement:** Hypothalamus regulates a wide spectrum of body functions.
**Analysis:** This statement is correct. The hypothalamus is a crucial part of the brain that connects the endocrine system with the nervous system and regulates various bodily functions, including temperature control, hunger, thirst, sleep, and hormonal regulation.

### Step 2: Analyze the second statement
**Statement:** Pituitary, pineal, testis, heart, and kidney are organized endocrine glands of the body.
**Analysis:** This statement is incorrect. While the pituitary, pineal, and testis are indeed endocrine glands, the heart is primarily a muscular organ and not classified as an endocrine gland. The kidney, although it has some endocrine functions (like producing erythropoietin), is primarily considered an exocrine gland because it produces urine.

### Step 3: Analyze the third statement
**Statement:** Hormones are non-nutrient chemicals and intercellular messengers.
**Analysis:** This statement is correct. Hormones are indeed non-nutrient chemicals that act as messengers between cells, facilitating communication and coordination of various physiological processes in the body.

### Step 4: Analyze the fourth statement
**Statement:** Luteinizing hormone helps in the maintenance of the corpus luteum after ovulation.
**Analysis:** This statement is also correct. Luteinizing hormone (LH) plays a vital role in the menstrual cycle and is responsible for maintaining the corpus luteum, which secretes progesterone after ovulation.

### Conclusion
After analyzing all four statements, we conclude that the second statement is incorrect.

### Final Answer
The incorrect statement is: "Pituitary, pineal, testis, heart, and kidney are organized endocrine glands of the body."
